rep_trigonometry_map_8bit_integer

Arguments:

  • _level_formula={ 0=sinusoidal | 1=cosinusoidal | 2=cubic-sinusoidal | 3=cubic-cosinusoidal | 4=cubic-sinusoidal-cosinusoidal },_multiplier>0,_valueshift,0>=_midgray_expf>=1,_lightness_merge_factor>=1,_lightness_end_expf>0,0>=_gray2col_end>=1

Description:

Map trigonometry function using 8-bit values. Remove _8i for non-8 bit values.

(equivalent to shortcut command (unknown)).


Note: Add 5 or 10 to _level_formula for another variation of the specified formula.

Default values:

_multiplier_a=1,_valueshift_a=0,_midgray_expf_a=1,_lightness_merge_factor_a=1,_lightness_end_expf_a=0,_gray2col_end_a=1
